This reminds me of the book Ringworld and the "Fall of Cities" - the civilization had become dependent on a particular superconductor, and wired it into everything. A microorganism that fed off of the superconductor came along and spread like wildfire. The side-effect was that it essentially wiped out the civilization because their entire energy infrastructure was built around this stuff.
I was thinking the same thing. Getting a colony of this stuff established in the voids and nether regions of say a wide body jet would not be a very good thing at all.
I imagine that jets are inspected often enough for something like this to be caught. I imagine that a bigger problem would be an infection getting loose in a manufacturing factory. How much of my laptop is edible?
Hopefully these guys know what they are doing :)
